Answer:
Step-by-step explanation:
Dimensions of the backyard is 14 m by 15 m
<u>The length of the fence is the perimeter of the backyard.</u>
- P = 2(l +w)
- P = 2(15 + 14) = 2(29) = 58 m
One meter of the fence costs $6.63
<u>Cost of the entire fence is:</u>
5/16 as a decimals. Divide 5 by 16 = 0.3125 times 100 = 31.25%
Answer:
k = 25
Step-by-step explanation:
(2x - sqrt(k) )^2 Expand this as a binomial
4x^2 - 4x*sqrt(k) + k The middle term must be -20x Solve for k so it is
-4xsqrt(k) = - 20x Divide by -4x
sqrt(k) = -20x/-4x Do the division
sqrt(k) = 5 Square both sides
k = 25
